45-4
Examples
This example shows how to set the sFlow sampling rate to 2048 on eth-0-1.
Switch# configure terminal
Switch (config)# interface eth-0-1
Switch (config)# sflow sample rate 2048
% Warning: sFlow sampling requires high CPU usage, especially with a low rate.
It is suggested not configure a rate less than default value 8192.
Related Commands
45.6 sFlow sample enable
Use this command to enable or disable packet sampling on individual port .
Command Syntax
(no|) sflow sample enable (input|output|both)
sflow: Set sFlow params
sample: Set sFlow packet sample
enable: Enable service
input: Input packet sample
output: Output packet sample
both: Both input and output packet sample
Command Mode
Interface configuration mode
Usage
Use this command to enable packet sampling on individual port. Input and output parameters are used to
specify the direction of packet sampling. Use the no parameter with this command to disable packet sampling.
By default, sFlow packet sampling is disabled in all ports. You can enable packet sampling for both input and
output direction.
If a packet is filtered by VLAN ACL, it will not be sampled by sFlow. This will happen in the case that a
sFlow-enabled switchport is without port ACL but with VLAN ACL. So, when packet sampling is enabled on a
switchport, a prompt will be given to info the potential of invalidation of packet sampling.
This command can only be configured on a port which is not a link-agg group member. The port can be either
a physical port or a link-agg port.
Examples
This example shows how to enable both input and output packet sampling on route port
eth-0-1 and enable output packet sampling on switchport eth-0-2.
Switch# configure terminal
Switch (config)# interface eth-0-1
Switch (config)# no switchport
Switch (config)# sflow sample input
